'ro ALL PERSONS To WHoM THESE 4PRESENTS SHALL COME;

Be it known that I, REUBEN'K. .HUNTOOIL of Boston, inthe county-ofSuffolk, and State of Massachusetts, have made a new and useful orimproved Governor for Engines ;v and do `hereby declare the same to befully described in the following specification, and represented in theaccompanying drawings, of which- Figure' l is a front elevation of it,as applied to the throttle-valveof a steam lengine.,.

Figure 2 is a vertical and transverse section of it.

Figure 3 is a horizontal section of the propeller cistern.

Figure 4 is a longitudinal section; and

Figure 5, a transverse Section ofV the throttle-valve and its case.

Figure 6 is a top view and Figure 7, an edge elevation of the propeller.p

In such drawings, A is a close cistern orvase, havingashaft, B`,extending down 4into it axially, and into a tubular bearing, C, arrangedon and so as to project upward from the bottom ofthe said cistern. Fixedto the said shaft, and arranged within the cistern, is ascrew-propeller, Outside of the outer edges of the blades of snchpropeller, the cisteru is provided witha series of vertical ribsor'wings, a da, which are projected from its inner surface, theybeing toaid in preventing the liquid used inthe cistern fromA being revolvedtherein by the pro'- 4peller while it may be in rotation. There is aprojection, b, on the outside of the tubular bearing O. In thisprojection, and leading into the space lwithin the bearing, is apassage, c, to which a stop-,c ockJ, is applied. The passage c opens acommunication between the interior of the cistern and the spaceimmediately beneath th'e shaft B, the stop-cock being to diminish thiscommunication, as circumstances may require, in order to let flowl intoand out of the said spacevmore or-less of the liquid in the cistern,While the shaft B and 4the propeller may be in revolution. In thc upperpart ofthe cistern A, and 'surrounding the shaft B, is a taperingdeilector, e, which, while the shaft is in revolution, operates bydeflecting the liquid throvvn upward by the propeller, to prevent theescape of such liquid through Vthe shaft-hole or bearing in the top ofthe cistern. The said 'shaft `B has a long gear, g, tix-ed on it. Thesaid Agear engages with another gear, L, fixed on a shaft, z', which isrevolved a belt proceeding from a pulley driven by the engine, to beregulated by my improved regulator. A-lever,`E, jointed to a link, F,which, at its `lower end, is jointed to a standard, G, bears on the topofthe shaft B, such shaft having a. spherical pivot or head, z', toenter a semi-spherical socket made in the lever, and provided with anoiling-hole, k. From the lever E a connecting-rod, H, (formed with ashoulder, K, and providedwith a series of weights, I, I', I, to restthereom) depends, and is jointed to an arm or crank, L, extending fromthe shaft M, of a throttle-valve, N. This throttle-valve is a hollowcylinder or conic frustum, open at one end and closed at the other, theclosed end being fastened to the shaft M, which runs through astning-box, O, of a val-vecas'e, P. The said'valve works in a tubularseat, R, which is surmounted by an annular passage, S. A conduit, 'T,leads out of the said annular space. Another conduit, U, leads out ofthe open end of the valveseat, the same being as represented;

Three rectangular openings, k 7c 7c, made through the valveradially, andat equal distances apart, operate with three l openings, ZlZ,'formedthrough the valve-seat. One'side of each of the openings l is crowned orarched, as shown at m, the same being to let the steam gradually intothe opening s. Steam from a boiler is to pass into the annular space S,and, after passing through the valve, is to go into and through theconduit l, to the valve-chest of the steam engine. On the propellerbeing put infrevolution within the cistern A,illed with a liquid, itwill rise in such liquid, and force the shaft B upward, and cause it toraise the lever E. The valve will be moved in the meantime so as todiminish the passages for the ilowage of steam through it. 'As the speedof the propeller may be increased by the engine, the steam passages ofthe valve and its seat Vwill be contracted; but on decrease of thespeed, the propeller will fall in the liquichand the valve passages'will be enlarged. .Thus the` amountof steam required to Work theengine, according 4the duty it may have to perform, will be regulated bythe governor. The bearing C, and its passage c, provided with astop-cock d, and opening intro the liquid space of the cistern, enableus to apply to the shaft B a force to` resist either its rise or itsfall, -or'that of the propeller. By such means applied'to the shaft andcistern of the propeller, we can control the rise or fall ofthepropellen'as circumstances may require; for, as we may turn thestop-cock so as to interrupt the iiowage of -liquid into the chamberbeneath the shaft B, we shall bring to operate on the shaft more or lessatmospheric pressure, and more or .less friction of `the liquid inpassing the cock, to resist the upward movement of4 the y raft. Thedescent of the shaft will be impeded by the liquid drawn .into/thevacuum chamber, such liquid aking its escape slowly through the cock.

I claim the combination of thebearing C, its passage e, and stop-cock d,with the shaft B, the propeller D, id the cistern or vessel A, arrangedas and for the purpose set forth. v

I also Claim the combination and arrangement of the deilector e, withthe eist'ern A, the shaft B, and the ropeller D, arranged as and for thepurpose set forth.

I also claim the Vcomb'ir'xation.and arrangement of the wings a, withthev cistern A, the shaft B, and propeller "L arranged as set forth.
